Step 2: Validate values using the "Func‐
tional Safety" wizard
Values for the validation Enter validated value
① Device identification data (if Function‐
al Safety is enabled via remote oper‐
ation)
● Long tag
● Product name
● Serial number
The values can be found on the rat‐
ing plate of the device and are dis‐
played via the wizard.
② Safety-related parameters
S1 Primary variable Pressure (the parameter cannot be
changed)
S2 Damping value 0.01 s ... 100 s in increments of
0.01 s
S3 Lower range value The value is within the measuring
limits. You can find information on
the rating plate of the device or in
the section Technical data
(Page 191)
S4 Upper range value The value is within the measuring
limits. You can find information on
the rating plate of the device or in
the section Technical data
(Page 191)
S5 Application
● Linear, proportional to pressure
(PRESS).
● Linear, proportional to level
(LEVEL).
● Proportional to flow rate, two-
step linear up to the application
point (VSLN2 or MSLN2).
③ Fingerprint (only if Functional Securi‐
ty is enabled via remote operation)
The value is displayed using the
"Functional Safety" wizard.
Step 3: Fail-safe behavior
Validate the fail-safe behavior using the "Functional Safety" wizard
● Yes
● No
Enter the date of validation of the fail-safe behavior
Date when Functional Safety was enabled Signature
